I made a simple memo board with items I already had on hand. I know there are prettier ways to finish the back but since this is just going up on the wall, it didn't seem necessary. Instead of thumbtacks, I used thick sewing pins to coordinate with the fabric. The cardboard prevents the pins from poking the wall.

1. Trace circle on cereal box with inner hoop of embroidery hoop. Cut out circle.2. Cut fabric for embroidery hoop, leaving enough fabric to fold edges over on the back3. Fill back of hoop with batting/stuffing.4. Put cardboard over back of hoop and tape fabric down. Use end of scissors to push in any stuffing that sticks out.
